GRADER.

SPECIFICATION forming part of Letters Patent No. 695,781, dated March18, 1902. Application filed October 3, 1901. Serial No. 77,387. (Nomodel.)

To all whom. it may concern.-

Be it known that I, JOHN BAGLEY, a citizen of the United States, and aresident of Tacoma, in the county of Pierce and State of Washington,have invented a new and Improved Grader, of which the following is afull, clear, and exact description.

This invention relates to an apparatus for scraping and hauling earth,such as is commonly used for grading, and is also applicable in ditchingand dredging; and it consists in certain features of constructionwhereby a more effective device is produced than those heretoforeemployed for the purposes above stated.

This specification is a specific description of one form of theinventionnvhile the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a plan view of a grader embodying my invention, and Fig. 2is a section on the line 2 2 of Fig. l.

The grader is made up of two side plates a, which lie in vertical planesparallel to each other and are imperforate to prevent the escape ofearth to the sides of the device. To the rear ends of the side plates isfastened, by riveting or otherwise, the end wall or bucket l) of thegrader. This is constructed of a sheet of metal curved around ahorizontal axis and presenting the concave side at the front of thegrader. At each transverse edge the end plate or bucket 12 carries ascraperblade 0, these blades extending transversely between the sideplates (6 and being set with a slight inclination outward to cause themto take hold on the ground. The blades 0 are fastened along their lengthto the edges of the bucket b, and at their ends they are joined bybrackets d to the side plates a. Between the front ends of the sideplates at extends a cross-brace a, holding them rigidly together.

f indicates a bail which is capable of connection with the front ends ofthe side plates a, adjacent to either edge thereof, by means ofclevis-like fixtures g. These fixtures g are held removably in place bybolts h, fitting in holes formed in the side plates, as shown.

To the bail c is connected the draft mechanism, which may be actuated bypower of any sort. For attaching to the grader the draft mechanism forhauling the grader backward a staple i is provided, and this may beremovably attached to the rear side of the bucketmeareither edgethereof,through holes formed in the bucket at the proper points.

In using the apparatus it is adjusted as in Fig. 2 and drawn over theground in the direction of the arrow. The lower blade 0 scrapes upearth, and this as it gathers in the bucket Z) is borne along with thegrader. When the end of the haul is reached, the grader is drawn back bythe draft devices attached to the staple 2' and a new drag or haul ismade. Then one blade becomes dull and worn, the fixtures g and 1 may bechanged to their other positions and the grader reversed; also, owing tothe construction employed the blades may be readily removed for repair.It will also be understood that the scraper may be made in varioussizes, according to the nature of the work to be performed.

Having thus described my invention, I claim as new and desire to secureby Letters Patentr 1. A grader, having vertical side plates, meansrigidly connecting their front ends together, a rear end plate extendingbetween the side plates and curved around a horizontal axis presentingthe concave side to the front of the grader to form a bucket, bladesextending along and secured to the longitudinal edges of the rear endplate, brackets fastened to the ends of the blades and to the sideplates at points adjacent thereto, and draft devices adjustablyconnected to the grader, for the purpose specified.

2. A grader, having vertical side plates, the top and bottom edges ofwhich extend essentially parallel to each other, thus giving the platesuniform width, means connecting the front portions of the side platestogether, a rear end plate extending between the side plates and curvedaround a horizontal axis presenting the concave side to the front of thegrader to form a bucket, the top and bottom edges of the rear end platelying approximately in the plane of the top and bottom edges of the sideplates, and draft devices capable of attachment to the front portions ofthe side plates adjacent to either edge thereof, for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN BAGLEY.
